Progress of mesoporous silica nanoparticles in targeting drug delivery system of antitumor drug / 中国中药杂志

ABSTRACT

Currently, chemotherapy is one of the main therapy for cancer. But the traditional antitumor drugs are systemic distribution in vivo, they are difficult to achieve an effective drug concentration in the tumor tissue and don't have the ability to distinguish normal cells and tumor cells by themselves, that cause systemic toxicity easily and can not meet the clinical needs. With the research on mesoporous silica nanoparticles (MSNs) deepening, more and more attention in the drug delivery system have been payed to in recent years, because of its unique physicochemical structure characteristics, it has the effect on specific targets, directly inhibits the tumor cell growth, reduces the side effects to normal cells, tissues and organs and can be long-term medication, etc. It is expected to be excellent carriers of antitumor drugs. MSNs application in the field of cancer treatment has now become a hot research field of medicine. In this paper, the latest research about MSNs in antitumor drugs targeting delivery system from 2008 to 2015 is summarized, including the application of MSNs separately in antitumor drug targeting, passive targeting, active targeting, physical or chemical conditions response targeting and other compound targeting drug delivery system. We expect it to provide a reference to the toxicity reducing and efficacy enhancing and further development of chemical medicine, natural medicine and monomeric compound of chinese herbal medicine.
